Denevue's performance is good, nothing more, but the story is dead in the water right from the beginning. The son is never properly introduced, except in a brief scene as a annoying dork and then he's dead. Bam! Eight minutes into the film he's croaked on over to the other side and I feel nothing at all. Deneuve quickly takes interest in the friend and turns him into her pet project: giving him a job and getting him back in school. Soon she starts with the stalking, the touching and the acting like a crazy person, but not crazy enough to make it interesting. Other boring stuff happens but it's all unimportant and the entire film just drags along like a two-legged turtle until the disappointing ending.
Unless you're just a hardcore Deneuve fan then I cannot think of any reason to watch this film.
